Initialization Parameters and Tape Archival

The unit name used for allocation is specified on the STORGRPn(0-9) initialization parameter. The TVSER1 and TVSER2 sub parameters can be specified to assign a range of tapes for CA View to use. The MAXGENT initialization parameter can be used to limit the number of generations of SYSOUT that are written to the same tape volume.

As part of its backup cycle, CA View uncatalogs any tape that is no longer needed.

Note: Tapes created by the backup cycle do not uncatalog until all of the following conditions are true:

• All reports are expired
• The tape is older than five days
• The highest generation on the tape is less than the current generation minus the NGENI initialization parameter value

The EXPDT initialization parameter can be used to determine when a tape is available for scratch.
